No. 835,079. Specification of application filed January 9,

To all whom it may concern.-

Be it known that I, BOGUMIL WENZES- LAWQWITSCH ITEDSELSKI, a subject ofthe Emperor of Russia, residing at 1 Proinisehlennayastrasse, Riga,Russia, have invented certain new and useful Improvements in lovers orearing-Surfaces for \Vheel-Tires and other Objects Exposed to fear; andI do hereby deelare'the following to be a full, clear, and exactdescription of the invention, such aswill enable others skilled in theart to which it appertains to make and use the same.

The object of this invention is to insure the greatest possibledurability in solid indiarubber tires furnished with Woven layers ofthread or fiber.

India-rubber tires with embedded strips of woven material are alreadyknown in various'forms. Inf'oneof these forms bands are laid paralleladjoining one another in the longitudinal direction of the strip. Thesebands are eutobliquely to the direction of the threads, whichconsequently take an oblique position in relation to the surface.Hereby, it is true, an unequal strain in the direction' of the threads,as also wearing out of "he upper surface, is prevented; but the'weariugaway of the two side surfaces is facilitated, as with constant use thewoven strips which happen to lie parallel to the side surfaces of thestrip become exposed and loosened. If only a few threads be loose, thesurrounding layer of woven material will become loose in a short time.

In the present invention the threads of the embedded woven layers runobliquely to all four external surfaces of the tire, so that even whenthe tire is worn only ends of the threads become visible on the treadand on, the side surfaces; but whole three ds cannot possibly come out.

Referring to the accompanyingdrawin'gs, Figure 1. isa perspective viewof a block of superposed layers of material pressed together. Figs. 2and 3 illustrate strips out Batented Nov. 6, 1906.

from'the block, and Fig. 4 illustrates a fur- 4 ther division andarrangement of the strips. The covering is prepared in the followingmanner: The hairs or threads in the form of run obliquely to the surfacewith their ends showing only above and below, but ,completely exposed atthe sides h. From the strips b thus obtained cross-strips p are outalong the line lc (shown in Fig. 3) and adhe- ,sively and firmly joinedtogether by their ends h, Fig. '4. In this way a tire-covering isobtained in which only the ends of the threads forming the layers arevisible on all four sides, Fig. 4. The vulcanizing may be effected priorto or subsequently to the. cutting. What I claim, and desire to secureby Letters Patent, is

A process. of producing solid indie-rubber;

vehicle-tires with inserted woven layers, e01.

sisting in embedding wovenjmaterial' in sheets of indla-rubber,superposing the sheets to form a block, cutting the block diagonallyinto strips 1), adhesively and firmly joining the ends of the strips,cutting the striqs so formed transversely, and joining the i." (ultingcut portions together by their ends'to produce a tire in which thethreads of the woven material run obliquely to all four externalsurfaces.

" In testimony whereof I have aflixed signature in presence of twowitnesses.
